  Trouble with vector input for polygon selection
Posted by: ss32 - 02-11-2018, 09:57 PM - Forum: Scripting questions - Replies (2)

I'm writing a plugin to call python-fu-heal-selection with inputs of the file and the points defining the polygon selection, but cannot get the polygon selection to work.  I have tried using the square polygon select and it works fine, but the generic polygon selection does not accept my input; what's wrong with my script?

Code:
(define
    (heal-select points point_count)
    
    (let*
        (
            (image         (car (gimp-file-load RUN-NONINTERACTIVE "tmp.jpg" "tmp.jpg")))
            (active-layer     (car (gimp-image-get-active-layer image)))            
        )                                            
        
        ;(gimp-image-select-rectangle     image CHANNEL-OP-ADD 122 67 138 81)    
        (set! active-layer (car (gimp-image-get-active-layer image)))    
        (define path-points (list->vector points))
        (gimp-image-select-polygon     image CHANNEL-OP-ADD point_count path-points)
        (python-fu-heal-selection     RUN-NONINTERACTIVE     
                                        image
                                        active-layer
                                        3
                                        0
                                        1)                                            
        (display points)
        (gimp-file-save RUN-NONINTERACTIVE image active-layer  "tmp2.jpg" "tmp2.jpg")
        (gimp-image-delete image)
    
    )
)

With the command line input:
Code:
gimp -i -b "(heal-select '(122. 67. 138. 67. 138. 81. 122. 81. 122. 67.) 5)" -b "(gimp-quit 0)"

I have tried removing '(define path-points (list->vector points))' and passed it the points as #(1 2 3  4) and still get an error message hinting at the fact that the polygon isn't closed or is empty.

Photo Creating 4k Image; Advanced Options X/Y Resolution
Posted by: Artisflowing - 02-11-2018, 01:59 AM - Forum: General questions - Replies (3)

Hello everyone!

When you are creating a new image and specifying the size. In the advanced options if I want to make something at 4k resolution should I bump up the resolution in the advanced options?

   

Thanks in advance for the informationSmile

  can't remove guide lines
Posted by: gib65 - 02-10-2018, 05:40 PM - Forum: General questions - Replies (6)

Hello,

I have a couple guide lines on my canvas that are misplaced and annoying me, but I can't seem to get rid of them:

[Image: guide lines.png]


From what I recall, I think I should be able to hover over them, and the mouse icon should turn into a grabby thing that indicates I can click and drag the guide lines over to the ruler where they will disappear, but it's not doing so. For example, if I'm on the pencil tool and I hover over the guide line, the icon remains the pencil tool. If I click on the guide line, I just create a mark like the pencil tool is supposed to do. Thus, I can't seem to get rid of them.

Do I need to activate a specific tool in order to grab them or make them disappear? Is there some other way of making them disappear? Am I remembering correctly (that the mouse icon should turn into a grabby thing) and my instance of Gimp is somehow corrupt?

Thanks.

  Cropped Corners
Posted by: le_jank - 02-09-2018, 07:01 PM - Forum: General questions - Replies (15)

Hello everybody (: I am trying to create a selection and an image with square/rectangles with cropped corners. Something like this:

[Image: b22024fd055d321772943efafac45311--battle...-viper.jpg]

All I can find is how to make rounded corners, but that is not exactly what I need. Does anyone have a clue on how to achieve this?

Question Importing Layer Changes Color
Posted by: mattig89ch - 02-09-2018, 04:38 PM - Forum: General questions - Replies (2)

Hello all,

First time here.  In truth, I don't do alot of image editing.  Dangit Jim, I'm a network tech not a graphic artist!

But I had an idea for a custom morale Badge, that I wanted to try and get made for me.  All the people who make said badges, wanted an image to base their printing/embroidering off of.

And thus here we are.  Right now, I managed to figure out how to get image 1's background to be transparent.  But, when I add it as a layer on top of image 2, image 1's colors change.

Is there a way to either re-color image 1 to its original colors?  Or a way to lock image 1's colors, so they don't change?

Thanks all!

  Exported Image Black Background
Posted by: avalier - 02-08-2018, 09:01 PM - Forum: General questions - Replies (2)

When I export this image, it is on a transparent background in Gimp and the PNG has a black background? 

If I use Black Text, it cannot be seen on the PNG. 

So if I  send this off to a printer, there is no text, and will the black background be present which will mess up the printing because I need it to be Transparent.

  Using Brightness-Contrast color tool in grayscale mode image
Posted by: Ambulation - 02-07-2018, 05:02 AM - Forum: General questions - Replies (2)

I've been working in an image set to grayscale mode. It's in preparation for a publication that will only accept images that are naturally grayscale in this mode (these are from a scanning electron microscope-all pixels assigned grey values only). I'm working in the most up to date version of GIMP-2.8.22 in Win7.

There are some layers in which I wish to make minor edits to the brightness and contrast, but the tool makes no visible change to the layer (which is in a layer group) I have selected. There are no changes in the preview mode or when i press OK. Is it possible this feature is not usuable in greyscale, but only RGB mode?

  Converting path/selection to single stroke?
Posted by: ringo.r81 - 02-06-2018, 10:44 PM - Forum: General questions - Replies (5)

Hi, I'm looking for a way to convert a path to a single line:
I have a scanned image. I used the "select by color" tool to select the outline. I then convert selection to path. Is there any tool or script that will change the path to a single line, rather than the outlines that the selection followed?

This whole thing is an attempt to get an image file that will allow me to DRAW/WRITE my own images with a Cricut machine, rather than print & cut or simply cutting the images out. I was told that I'll need to find a way to save a file as a "single stroke" vector image. If anybody knows another way to go about this, please let me know! I feel like I'm being pretty dense about this...  Huh
